In Hindu tradition, Sunday is dedicated to Surya Dev, the Sun God, who symbolizes strength, health, and success. Jaggery and wheat are considered auspicious offerings used in rituals and donations to enhance the Sun's influence. Practices like offering wheat and jaggery to the needy or performing Surya Arghya with jaggery and red sandalwood are believed to improve luck, remove obstacles, and bring positive changes in career and life.
